However, his CT scans of ancient mummies in the Egyptian Museum in Cairo showed that the mummies' arteries clearly had plaque buildups. He says they were quite similar to those of a contemporary American.

According to Miyamoto, the mummified people probably ate a fair amount of meat, and salt was commonly used to preserve food. Excess salt contributes to vascular disease.

Miyamoto says his findings show that humans appear to be genetically inclined to develop arterial sclerosis, however he adds that unhealthy diets should still be avoided.
